Magnetic Gradient Fluctuations from Quadrupolar Ge in Si/SiGe Exchange-Only Qubits
J. Kerckhoff, B. Sun, B. H. Fong +14
We study the time-fluctuating magnetic gradient noise mechanisms in pairs of Si/SiGe quantum dots using exchange echo noise spectroscopy. We find through a combination of spectral…

Spin-Blockade Spectroscopy of Si/SiGe Quantum Dots
A. M. Jones, E. J. Pritchett, E. H. Chen +15
We implement a technique for measuring the singlet-triplet energy splitting responsible for spin-to-charge conversion in semiconductor quantum dots. This method, which requires fas…
